I don’t usually write reviews unless a product really impresses me—good or bad. In this case, it’s the former. I recently picked up the A850GL 850W power supply for my new PC build, and I have to say, I’m genuinely impressed with the overall quality and performance of this unit. Right out of the box, the PSU feels solid. The packaging was minimal but protective, and the unit itself has a sleek, matte black finish that fits nicely in my Fractal Design case. One thing I appreciated was that it came fully modular, which really helps with cable management. All the included cables are flat and flexible, making routing them behind the motherboard tray a breeze. Another thing worth mentioning is the 80+ Gold certification. It’s nice knowing that the power efficiency is solid, and I’m not wasting unnecessary power or generating excess heat. It also gives me a bit more peace of mind in terms of longevity and stability. I haven’t noticed any voltage dips or instability, even during heavy GPU use. Overall, the A850GL is a great value for the price. It feels like a premium product without the premium markup. If you’re building a mid-to-high-end rig and want something efficient, quiet, and dependable, this PSU definitely deserves a spot on your shortlist.

I’ve been using the MSI MPG A1000G PCIE5 for a few weeks now, and so far, it’s been a solid performer. It supports PCIe 5.0 and ATX 3.0 standards, which is useful if you're planning to run newer GPUs that require the 12VHPWR connector. Having that built-in is definitely convenient.The build quality is good, and the modular design makes cable management easier. The included cables are decent quality and long enough for most mid- to full-tower builds. It's also quiet — the fan rarely spins up to noticeable levels, even during gaming or heavier workloads.Efficiency is in line with its 80 PLUS Gold rating, and I haven’t experienced any stability issues so far. It’s not the cheapest option out there, but for those wanting a bit of future-proofing, it’s a good solid option, I bought another one for my second rig.Overall, it's a dependable power supply that does what it claims without fuss. Not flashy, but gets the job done.

At £109.99 I personally feel it’s an amazing price and with a 10 year warranty over the 7 year you get with the MAG PSU for an extra £10 I feel it’s a no brainer
